Abstract: 935,341. Sewing machines. FILOTECNICA SALMOIRAGHI S.p.A. Feb. 5, 1960 [Feb. 19, 1959], No. 4165/60. Class 112. A sewing machine is provided with control means adapted to reverse the direction of rotation of a driving shaft which is connected to a driven shaft by a clutch so arranged that torque is transferred to the driven shaft only when the driving shaft rotates in such a direction as to cause the machine to perform a sewing operation. The invention is embodied in a portable, free-arm sewing machine, all the working parts of which are contained within an open-fronted housing conprising a standard 1, an upper arm 2, at free arm 3 and a base 4, the front being closed by a plate 69 secured in position by screws 70. The free end of arm 3 is closed by a hinged cover 42. An electric motor 5, mounted in the base, has a shaft 9 on which is journalled a pulley 8. A helical spring 62, wound upon an extension 62<SP>1</SP> of pulley 8, has an end secured by a screw 61 to a sleeve 60 rigid with shaft 9, whereby the latter transmits torque to pulley 8 when rotating in one direction only. Shaft 9 projects outwardly of the machine frame to provide a spigot 19 for holding a bobbin 65 to wind the latter during reverse rotation. Pulley 8 is coupled to a shaft 6 in arm 3 by a belt 7. Shaft 6 is coupled by reduction gearing 12, 13 to a shaft 11, and the latter is coupled to the upper arm shaft 17 by a belt 14. A doublearmed lever pivoted at 45 above shaft 17 has the end of one arm 44 positioned above the presser bar 47, while the end 51 of the other arm abuts the leaf spring actuator 53 of a micro-switch 54. Raising of the presser bar thereby lowers end 51 to operate switch 54 for reversing the rotation of motor 5 to disconnect the drive. Arm 44 simultaneously raises the spindle 57 of the thread tensioner 58 to release the thread tension. A triangular cam 23 on shaft 17 has an inclined end face 24 engaged by a roller 30 carried by the upper end of a lever 28 pivoted on a fixed pin 29. The lower end of lever 28 is connected by a pair of resilient bars 32 to a member 27 carrying the feed dog 25. Oscillation of lever 28 on rotation of shaft 17 thereby effects feed lift movement. Cam 23 is embraced by the forked upper end of a bar 33, the lower end of which is pivoted to an offset portion of a bar 35 pivoted on shaft 6 by means of lugs 36. A pin 39 fixed to bar 35 is journalled in a lug 40 carried by member 27. The position of bar 28 is adjusted by means of. a conventional linkage from an external knob 37, whereby bar 35 is appropriately oscillated for imparting advance or return movements of required magnitude to the feed dog 25 via the flexing of the bars 32.

Title: Improvements in or relating to combined electromagnetic and thermal relay arrangements
IPC: H01H51/32
Filed: 1937-02-16
Abstract: 489,118. Electrically-tripped switches; actuation of switches ; electric control systems. GENERAL ELECTRIC CO., Ltd., COLLYER, J. E., and SMART, N. C. Feb. 16, 1937, No. 4581. [Class 38 (v)] [Also in Group XXXVIII] In a device which may be used for turning street lamps on and off by currents of suitable frequency superimposed on power lines or led along pilot wires, current of a certain frequency causes the vibration of a reed which releases a contact controlling a slow acting relay controlling the lamps and current of another frequency causes the vibration of another reed which releases a contact serving to move the slow acting relay back into its original position. In the form shown in Fig. 2, energization of a coil 21 by a current of suitable frequency vibrates a reed 18 which tilts a lever 15 which frees a contact spring 14 which moves to the left closing one or more contacts. A motor 1, continuously driven, rotates a cam 4 which periodically tilts a lever 7, 8 and moves the contact springs 11 back so that the spring 14 is relatched as soon as the signal current to the coil 21 ceases. Fig. 2 shows a spring set with several contact springs 11 but in the simplest form there are only two, and the closing of these, Fig. 3, closes a circuit to one of the two heating windings of a thermal relay 27 of the type described in Specification 481,774. The arrangement is such that the relay 27 is not actuated by transient surges of current Energization of the coil 21 by current of a different frequency vibrates a second reed and closes contact springs 12 in a similar way. This returns the relay 27 to its original position. The contact spring set 11 shown in Fig. 2 forms part of a system, Fig. 4 (not shown), in which the motor 1 is only energized after the signal current is received, and in which the lamps are turned off should currents of " on and " off " frequencies be simultaneously applied. In another arrangement, the motor has two windings. In a further modification a motor tends to rotate the housing of a differential gear the two side wheels of which carry ratchet wheels held fast by pawls adapted to be tripped by the vibration of the tuned reeds. When a wheel is released it rotates and by means of a cam opens and closes the associated contact springs.
